CROSS REFERENCE TO RELATED APPLICATION

This application is a divisional and claims the benefit of U.S. patent application Ser. No. 15/721,168, filed Sep. 29, 2017 and entitled “METHOD AND SYSTEM FOR DISPLAY ASSEMBLY HINGING,” which is hereby incorporated by reference in its entirety.

BACKGROUND

The embodiments described herein relate generally to electronic equipment cabinets and, more particularly, to electronic gaming machines (EGM) including counterbalanced hinge assemblies for securing one or more displays proximate the EGM.

At least some known EGMs include a display, also referred to as a monitor or a screen, within a cabinet housing at least a portion of the EGM. Additionally, other displays may also be associated with the EGM and be located proximate the EGM, but may not form an integral part of the EGM. For example, a lower display may be located next to the EGM and an upper display may be located above the EGM. The upper display may be positioned high above a flooring surface on which the EGM is positioned that maintenance personnel may have difficulty reaching the display comfortably without the use of a step ladder or other elevating device. For example, replacing and/or installing the display may require a maintenance technician lifting a monitor, which may weigh in excess of fifty pounds, above the level of his head to position the monitor in its mounted position. Climbing the elevating device while carrying the display may comprise the work safety of the maintenance technician.

DETAILED DESCRIPTION

The following detailed description illustrates embodiments of the disclosure by way of example and not by way of limitation. It is contemplated that the disclosure has general application to physical and methodical embodiments of a monitor hinging mechanism in industrial, commercial, and residential applications.

Embodiments of a monitor hinging mechanism are described herein. The monitor hinging mechanism provides an improved motion controlling hinge device, which effectively counterbalances the weight of a display member mounted in a monitor frame throughout an operative arc of its movement; automatically compensating for the variable torque (due to gravity) effects on the monitor frame as it swings between a horizontally extending and a vertically standing attitude with respect to the floor surface.

The following description refers to the accompanying drawings, in which, in the absence of a contrary representation, the same numbers in different drawings represent similar elements.

FIG. 1 is a front elevation view of an overhead display assembly 100 for an electronic machine 102. In the example embodiment, electronic machine 102 is a plurality of electronic gaming machines (EGMs) ganged together in an island formation. Plurality of electronic gaming machines are the type of electronic machine at which players play games with game play media, and which pay out game play media to players as a prize. In various embodiments, electronic machine 102 may be a single stand-alone electronic machine 102 or may have any number of electronic machine 102 associated with each other by proximity whether in an island formation or not.

Overhead display assembly 100 includes a display monitor 104 supported in a monitor frame 106 at least partially surrounding display monitor 104. Monitor frame 106 includes a plurality of legs 108 coupled around an opening 109 through which a respective display monitor 104 is viewable. Overhead display assembly 100 is configurable in several different arrangements. Each display monitor 104 may be associated with a respective one of a plurality of EGMs 102 as shown in FIG. 1.

A single display monitor 104 may be associated with more than one or all of the plurality of EGMs 102 as shown in FIG. 2. In the example embodiment, overhead display assembly 100 extends vertically above the plurality of EGMs 102 in an operational position 111 as shown. As will be shown below, overhead display assembly 100 is not supported by plurality of EGMs 102 or by a pedestal 112 on which plurality of EGMs 102 are positioned and supported. Rather, overhead display assembly 100 is supported separately from plurality of EGMs 102 and pedestal 112 using a support stanchion 114 that can only be partially seen in FIG. 1. In various embodiments, support stanchion 114 is supported by a floor surface 116 or a wall surface 118. In other embodiments, support stanchion 114 is supported by a false floor assembly 120 (not shown in FIG. 1).

FIG. 2 is perspective view of overhead display assembly 100 incorporating a single display monitor 204 for plurality of EGMs 102. Overhead display assembly 100 may include a plurality of display monitors ganged together using a linear fixture 202 extending across an edge of each of the plurality of display monitors 204. In various embodiments, linear fixture 202 includes an attraction lighting device 206.

FIG. 3 is a side elevation view of overhead display assembly 100 in operable relation to plurality of EGMs 102 and pedestal 112. In the example embodiment, support stanchion 114 includes a first anchor end 302, a second coupling end 304, and a stanchion body 306 extending therebetween. First anchor end 302 is configured to couple to a supporting structure, such as floor surface 116. Second coupling end 304 is configured to couple to a counter-balanced hinging mechanism 308. In other embodiments, support stanchion 114 is coupled to and supported by one or more braces 310 coupled to wall surface 118, in which case support stanchion 114 may not extend to floor surface 116. Counter-balanced hinging mechanism 308 permits monitor frame 106 and display monitor 104 to be positioned in operational position 111, a maintenance position 311, or any of a plurality of intermediate positions between operational position 111 and maintenance position 311 along an angle 312. In the example embodiment, angle 312 is greater than 30° such as, but not limited to approximately 90°. In some embodiments, operational position 111 may be other than vertical, which would typically make angle 312 an acute angle, or an angle less than 90°. Additionally, monitor frame 106 and display monitor 104 may be positioned such that angle 312 is obtuse, or greater than 90°. As will be discussed in greater detail below counter-balanced hinging mechanism 308 is configured to balance the force applied to monitor frame 106 and display monitor 104 by counter-balanced hinging mechanism 308 and a moment of monitor frame 106 and display monitor 104 at any of the plurality of intermediate positions between operational position 111 and maintenance position 311. Such counter-balancing of forces and moment permits monitor frame 106 and display monitor 104 to be manually translated between operational position 111 and maintenance position 311 and maintain the intermediate position when the manual urging is ceased.

FIG. 4 is a side elevation view of a portion of overhead display assembly 100 illustrating a lower portion of monitor frame 106 in operational position 111 and second coupling end 304 of support stanchion 114. FIG. 5 is the side elevation view of a portion of overhead display assembly 100 illustrating a lower portion of monitor frame 106 in maintenance position 311 and second coupling end 304 of support stanchion 114. In this embodiment, counter-balanced hinging mechanism 308 includes a single hinge pivot axis 402 and is counter-balanced using a strut 404, such as a fluid cylinder and piston arrangement. Other force producing devices may also be used for force-balancing, for example, electrical and fluidic linear actuators, bias members, including linear springs, torsion springs, and the like. Strut 404 is sized and positioned to generate a balanced-force 406 that is predetermined to counter the moment 408 of monitor frame 106 between operational position 111 and maintenance position 311 and to “lock-in” monitor frame 106 at operational position 111 and maintenance position 311.

FIG. 6 is a perspective view of a counter-balanced hinging mechanism 308 in accordance with another example embodiment of the present disclosure. FIG. 7 is a side elevation view of counter-balanced hinging mechanism 308 in operational position 110.

A first and a second pivot plate 504, 506 are coupled to L-shaped support bracket 502 edge-wise and each includes a pair of apertures 508, 510, 512, 514. Apertures 508, 510, 512, 514 are configured to receive a bias member, such as, a torsion bar or torsion spring style torque engine configured to apply a variable amount of force to arm linkage assembly 524 and/or arm linkage assembly 526, the variable amount of force maintains monitor frame 106 stationary in an intermittent position between operational position 110 and maintenance position 311 respective torsion bar or torsion spring style torque engine 516, 518, 520, 522. A first arm linkage assembly 524 operatively couples torque engines 516, 518, together and a second arm linkage assembly 526 operatively couples torque engines 520, 522 together. A cam roller 528, 530 extends outwardly from respective ones of first arm linkage assembly 524 and second arm linkage assembly 526. A hinge plate 532, 534 is coupled edgewise to a respective pivot plate 504, 506. A cam 536, 538 is coupled to monitor frame 106 (shown in FIGS. 1 and 4) and to a respective hinge plate 532, 534 through a pin 540, 542 and a spacer 544, 546. Cam roller 528, 530 is configured to engage a cam surface 548, 550 of cam 536, 538.

In various embodiments, overhead display assembly 100 includes counter-balanced hinging mechanism 308 having a single pivot point as shown in FIGS. 4 and 5. In other embodiments, overhead display assembly 100 includes counter-balanced hinging mechanism 308 having at least two pivot points as shown in FIGS. 6, 7, and 8.

FIG. 9 is a flowchart of a method 900 of maintaining a display assembly for an electronic machine wherein the display assembly includes a monitor frame coupled to a counter-balanced hinge assembly. In the example embodiment, method 900 includes positioning 902 the monitor frame in an approximately horizontal attitude with respect to the floor surface using the counter-balanced hinge assembly, aligning 904 an outer edge of the display assembly with an inner surface of the monitor frame, translating 906 the display assembly to a seated position within the monitor frame, and rotating 908 the monitor frame to an approximately vertical attitude with respect to the floor surface by applying a manual force to the monitor frame.

Optionally, method 900 further includes maintaining the monitor frame in an intermediate position between the approximately horizontal attitude with respect to the floor surface and the approximately vertical attitude with respect to the floor surface using the counter-balanced hinge assembly when the manual force is removed at the intermediate position. Method 900 also may include applying a counter-balancing force to the monitor frame by the counter-balanced hinge assembly that is equal to a moment of the monitor frame. In various embodiments, the display assembly includes a plurality of monitor frames coupled to the counter-balanced hinge assembly and method 900 further includes ganging the plurality of monitor frames together using a fixture coupled to a periphery of the plurality of monitor frames.
